Oh, boohoo Wes.. I certainly hope this is not true.
My gosh... toughen up... suck it up... and work through whatever issues you have. Again, if this is the issue I'm true disappointed in his character.
If you are unhappy, don't beat around the bush... hit it head on and address it... work on it... be a part of the solution. To throw out some "I'm unhappies" and then feel that it's up to a coach to pull you out of it... or you'll quit... is childish and immature at best.
So, the next coach doesn't make him happy, and he runs again??? I know he's still a young man, but I hope he figures things out soon. If running away is his mantra then he's got bigger issues than finding a program of cotton candy hills and gumdrop rain.
